I don't think AI is comparable to cars. The problem with cars is that they necessarily use the commons. The more roads you build, the less space you have for trains, parks, housing, etc. AI isn't like that. I can continue to think for myself and look for ways to add value as a human even if everyone around me is using AI. And if that fails, if I can't find a way to compete with AI, if AI really is capable of doing everything that I can do as well as I can do it, why would I not want to use it?
